26 -- This child package contains the routines to translate a unit name to | |
27 -- a file name taking into account Source_File_Name pragmas. It also | |
28 -- contains the auxiliary routines used to record data from the pragmas. | |
29 | |
30 -- Note: the reason we split this into a child unit is that the routines | |
31 -- for unit name translation have a significant number of additional | |
32 -- dependencies, including osint, and hence sdefault. There are a number | |
33 -- of tools that use utility subprograms in the Fname parent, but do not | |
34 -- need the functionality in this child package (and certainly do not want | |
35 -- to deal with the extra dependencies). | |
